Want some premium headphones and have money to spend? These over-the-ear headphones from Sennheiser fit the bill. They come with high quality sound, noise cancelling, what they call transparent hearing functionality (so you can hear the noise around you), and a Bluetooth connected app that lets you control it all on your phone. Unfortunately they also had a pretty big security oops back in 2018. Here's hoping Sennheiser learned their lesson from that.

What could happen if something goes wrong

We love that Sennheiser doesn't collect any personal data on its users. What a novel idea! They did have a security problem in 2018 when Sennheiser’s flawed headphone software opened PCs and Macs to website spoofing, which isn't great. And, as always, if you use Google Assistant or Alexa with these headphones, that voice data is sent back to Google or Amazon. All in all though, we don't think Sennheiser's headphones should scare you much at all.

Headphone maker Sennheiser has patched its software after the company admitted a serious vulnerability that made it easy for hackers to impersonate any website — even encrypted pages.
